.T0 all whom t rmay concern:

Be it known that l, ANDREW SORENSEN, a citizen oi' the United States. and resident of Oakland, county of' Alameda, and State of California, have invented a new and useful lashing Machine, of which the following is a specification.

rThe present invention relates to improvements in washingmachines and its object is to provide a motor driven washing machine that can be conveniently used in coinoination with the ordinary wash tray found in most houses, so that water can be run into it directly from the faucets usually provided above the wash trays and the dirty water can be dumped out of the washing machine by merely turning the `same upside down, when the water runs into the tray which latter is usually connected with the sewer. A further advantage of my washing machine is that it can be attached to the tray without any diliiculty, no tools being necessary, the only fastening means being thumbscrews. Another advantage of my washing machine is that the clothes in the same are vwashed by the rockingJ motion ot' the drum alone and that no agitating means is used inside the drum.

ther objects and advantages of my chine will appear as the specification proceeds.

#l show `a preferred embodiment oit my invention in the accompanying drawingy in which Figure l represents a 'top plan view of my washing machine shown in its place in the tray, Figure 2 a side elevation of the same, part of the tray beingshown broken away, Figure 3 a cross-section through the same along line 3 3 oi Figure l, Figure l an enlarged perspective detail view of one ot' the bearings' for my washing machine, Figure 5 an enlarged perspective detail view of the other bearing for the same, and Figure 6 an enlarged detail view showing the connection between a connecting linlr and f an arm secured to the drum oi' my washin machine.

Referring to the drawings in detail. it will be seen that the clothes container in my washing machine is aV cylindrical drum (l) the ends of which are provided With metal reinforcing members' (2) :from which extend axialstuds (e) adapted to rest in bearings (6). .The drum is flattened on top,

as shown at 7 and has a preferably rectangular openlng in .the dat portion lwhich eX- @attested duly 2 Serial No. 77,95%

tends nearly over its whole surface. The opening fianged and fortified by angle irons (53), one leg (9) ot which rests on the rim defining the opening while the other leg (l1) toes downward into the drum. Two handles (12) are provided on these angle irons by means of which the drum may he conveniently gripped and rotated .or lifted out of the tray (14), The latter 1s an ordinary vash tray, preferable of Soncrete, hire it found in most houses, having a drain pipe (16) leading into the sewer and ordinarily provided with hot and cold water faucets. A cover (l5) is adapted to .tit in the opening` of the drum and is provided with a handle (20).

Two bearings (G) are provided in this tray tor the washinr machine, one at either end. The two are supported on metal members illustrated in Figures 5 and 6. @ne of them, having 'the numeral (i7), consists of a triangular metal plate (1S) having a flange (19) adapted to rest on one ot the edges of the tray (141). While the triangular por ion extends downward from the flange into the tray along its Wall and is firmly held in that position by a thumb screw (21) which extends through a bracket (22) projecting;l downwardly trom the flange (19) outside the wall of the tray. Small pointed projections (25) allow the plate to grip the wall ot the tray and prevent it from sliding. The ange further carries a'channel (23) toeing` upwardly and disposed transversely to the flange. This channel Iserves as a supporttor a motor (2e) and itstwo legs are provided with curved recesses (26) to provide a convenient bed for the motor. The shaft (2T) of the motor is adapted to engage, through a clutch mechanism l(28), a shatt (29) alined with the same. which latter shaft is supported in a housing (3l) and ends into a worm in the housinof. The latter is integrally connectedwith e housing (32) running; trans verse to it and supported -in a perforated lug (33) risingfrom the surface ot the Harige (19). A setscrew firmly holds said housing in its place. ln the latter housing; is supported the crank shaft (36), one end of which is provided with a worm gear adapted to be engaged by the worm aforesaid while the other end carries the v.crank arm (37. to the tree end of which the connecting rod (38) is pivotally connected as shown at (32). The other end of kslot (42) the Connecting rod pivotally engages an arm (41), Figure G, which latter rises vertically from one end of"tlie drum, secured preferably to the fortifyinglmetalmember lt will be understood that, when the motor begins to work, rotary motion is transmitted to the crank shaft (36) through the worm and the worm gear referred to and this rotary motion transmits rocking motion to the arm (41), which on its hand transfers this rocking motion to the wash drum (l).

To provide some means for adjusting the intensity of the rocking motion of the drum, l secure the arm (41) adjustablyto the drum by providing a lslot (42) in the arm through which the bolt (43) extends which secures the arm to the drum. If a long rocking stroke is desired, the armcan be let down to the position shown in Figure Q, while-when a short stroke is wanted the arm can be raised so that the bottom of the shown in dotted lines in VFigure 2 comes 1n contact with the bolt.v

Attention is called to the special 'means i' be noticed that instead of the circular bearing ordinarily employed a recess (44) is provided in the underside ofthe connecting arm. This recess is used for the reception 'of the bolt (45), Figure 2, which is screwed into the arm (41). .recess I provide a latch (46') comprising a To secure the bolt in the metal rod bent to form a right angle, one leg (47) of which is guided underneath the connecting rod through two perforated lugs (48) provided between the end of the `connecting rod and the recess so as to just cover the latter, while the other leg (51) extends across the end of the connecting rod and rests ina small groove (52) in the end, when the latch covers the recess (42). Between the two lugs (48) a spring (.53) is secured 'around the leg (47) by a pin (54), which spring prevents the leg from being Withdrawn altogether, but allows a with drawagl'far enough to open the recess and -to allowthe boltl (4B) to slip put of the same.y lit will be seen that in thisl manner the cont meeting rod can be connected to the arm (41) ver f easily and quickly, the only necessary step being a pull on the portion (51) of the latch; y j i `The bearing (6) at the other end is supported in substantially the same manner as 'the other bearing, without the attachments necessitated by the power arrangement.

' 'Ehe detail' view in Figure 5 shows the triangular metal slate (56), the flange (57), t'bebg'/iet (58!) and the thumb-screw (59) Securing it tightly to the opposite lwall of the tray. rThe. two triangular metal plates (1R) and (5(3) are j'n'oridcd. in corresponding places. with thc U-shapcd bearing mcmbcrs .(Gl) on which the .studs protruding from the drum at either cnd are rockingly supported. 1
